DISH-WASHING MACHINE.

Application filed January 29, 1914. Serial No. 815,806.

To all whom it may concern:

Be it known that I, ERNEST BENEDICT, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Dish-Washing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to dish washing machines in which a spray of cleaning or rinsing water is brought dishes.

In machines of this character, the simplicity of parts and the ease of operation are of great importance, and it is the object of my invention to provide a machine of this character wherein the operation thereof is accomplished by the water, said water sent. at its own pressure through the machine,.

and accomplishing a shifting of the spraying devices so as to thoroughly cleanse the dishes. l fhis object and other advantages to be noted, I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings, Figure 1 is a perspective view of the machine with one side opened to show the interior construction. Fig. 2 is a plan view of one of the revolving pipes. Fig. 3 is a vertical section of the machine showing the pipes in elevation. Fig. 4 is a top plan view of the machine taken with the cover removed. I

1 is the base of the machine casing, which has a slope to the center, terminating in an outlet 2, which is to be connected to the house drain. The preferred structure of the casing portions is otherwise in the shape of a plain box, with aremovable lid 3, having a handle 4. Angle brackets 5, 5, are

mounted along the sides of the machine above the base, and on these brackets rests the dish supporting screen 6, which is easily removed for cleaning by lifting it out of'the top of the machine. On this screen are also preferably erected the dish supporting rings 7 and 8, which are held up by the posts 9 suitably secured to the screen, or merely resting thereon if the screen is of fine enough mesh.

Specification of Letters Patent.

in contact with the Pa e ar 2 e.

Secured against the side of the machine is a soaper 10 adapted to take water from the house mains and saturate it with soap. A valve 11 admits water to the soaper, and a valve 12 admits water around the soaper to the inlet pipe 13 of the machine. The inlet pipe extends in to the center of the casing and it is preferably located above the middle point thereof. It is provided with a T 14, into which are fixedly mounted the vertically alined pipes 15 and 16. These pipes might be in the shape of one pipe with a hole bored in it (not shown), but this need not be described, as it is purely an equivalent structure. The pipes which extend with one above and one below the screen 6, are provided at their outer ends with rev-* oluble couplings 17, 17, in which are suitably secured the horizontal pipes 18 and 19. The pipes are positioned so as to extend each way from the revoluble couplings and are provided with caps 20, 20, for closing their ends. Each pipe has two sets of openings, one set 21 which is directed toward the screen or dish rack 6, and the other set 22 at an angle thereto. The result of this will be that the water flowing out of the pipes will partially be projected directly against the dishes on the rack and the balance projected against them at-an angle so as to cause the revolubly -mounted -pipes to revolve. This revolution will cause the water to thoroughly wash the dishes at all points and at the same time will not seriously use up the water pressure or waste the water employed to impart the rotary motion to the pipes.

The operation of the machine is simple, and the various parts inexpensive and of easy replacement. First soapy water is sent through the pipes and then clean water for rinsing. The dishes may then be allowed to dry without removing them, as they are on the rack 6 which acts as a drain board.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

In a dish washing machine, the combination of a casing and an open rack for the support of the articles to be washed, a pair of vertically alined pipes and means for supplying water under pressure thereto, one of said pipes extending above and the other below the rack, a revoluble coupling for the Q' I i 1,170,125

outer end of each of said pipes with vertical obtained simultaneously with the rotation of axes therefor, said couplings provided with the'arms bythe discharge of water from the 10 laterallydextfinding'arns closged at the elnds, angularly disposed openings.
